Page guide

Put object keys in a consistent order without rearranging arrays.

How to use Sort JSON keys
  1. Paste valid JSON. Keys in every nested object are sorted with a case-sensitive character comparison. Copy or download the formatted result.
  2. The outer object orders a before z; the nested object orders b before y. Array items keep their original order. Integer-like keys follow JavaScript numeric key ordering.
